Gastrointestinal feeding and aspirating device for use in treating patients

Claim 2

A gastrointestinal feeding and aspirating device for surgical insertion into a patient's body through the abdominal and gastric wall, comprising: an aspirating lumen having an external end portion to be disposed outside the body, said external portion having an opening for connection to a source of suction and having an internal end portion to be disposed in the proximal segment of the small bowel, said portion having at least one orifice for intake of matter to be discharged from the body; a feeding lumen having an external end portion to be disposed outside the body, said portion having an opening adapted to receive food to be transported through the lumen and having an internal end portion to be disposed in the proximal segment of the small bowel, said internal portion having an orifice therein for the discharge of food; and means for securing the device to the patient's body through the abdominal and gastric wall such that the internal portion of each lumen is located in the proximal segment of the small bowel, said feeding orifice being maintained at a location which is substantially three inches downstream of the most distal aspirating orifice, the portion of each lumen between the securing means and that lumen's external opening being continuous.

Claim 3

The invention of claim 1 wherein said securing means further comprises: an inflatable member securely attached to the device to be disposed within the body; and an inflation lumen having an external end portion to be disposed outside the body and an inflation orifice communicating with the interior of the inflatable member, so that the inflatable member can be directed into the body while deflated and then inflated from outside of the body.

Claim 4

The invention of claim 2 wherein the device is made of polysiloxane.

Claim 5

The invention of claim 2 wherein the device is made of a material which is bio-compatible with the body.

Claim 6

The invention of claim 4 wherein the device is made of polyurethane

Claim 7

The invention of claim 4 wherein the lumens are bundled together in order to form one unitary gastrointestinal tube device.

Claim 8

The invention of claim 6 wherein the feeding lumen extends beyond the internal end of the aspirating lumen, the feeding orifice is an opening on the side of the interior end portion of the feeding lumen and the internal end of the tube device is closed and rounded.

Claim 9

The invention of claim 7 wherein the external end portion of the feeding lumen is adapted to receive a male luer fitting.

Claim 10

The invention of claim 8 wherein the inflation lumen and the feeding lumen are disposed on opposite sides of the aspirating lumen so as to be 180° apart from each other.

Claim 11

The invention of claim 4 further comprising: an additional stomach aspirating lumen having an external end portion to be disposed outside the body, said external portion having an opening for connection to a source of suction and having an internal end portion to be disposed in the stomach, said internal portion having at least one orifice for intake of matter to be discharged from the body.

Claim 12

The invention of claim 1 wherein the feeding orifice is downstream from the last aspirating orifice by a range of 2-4 inches.

Claim 13

A gastrointestinal feeding and aspirating device for surgical insertion into a patient's body through the abdominal and gastric walls, comprising: an aspirating lumen having an external end portion to be disposed outside the body, said external portion having an opening for connection to a source of suction and having an internal end portion to be disposed in the proximal segment of the small bowel, and a mid-portion adjacent to the internal end portion to be disposed in the stomach, said internal end portion and said mid-portion each having at least one orifice for intake of matter to be discharged from the body; a feeding lumen having an external end portion to be disposed outside the body, said portion having an opening adapted to receive food to be transported through the lumen and having an internal end portion to be disposed in the proximal segment of the small bowel, said internal portion having an orifice therein for the discharge of food; and means for securing the device to the patient's body through the abdominal and gastric walls such that the internal end portions of the aspirating lumen and the feeding lumen are located in the proximal segment of the small bowel, and said mid-portion of the aspirating lumen is located in the stomach, said feeding orifice being maintained at a location which is substantially three inches downstream of the most distal aspirating orifices, the portion of each lumen between the securing means and the lumen's external opening being continuous.

Claim 14

A gastrointestinal feeding and aspirating device for surgical insertion into a patient's body through the abdominal and gastric walls, comprising: an aspirating lumen having an external end portion to be disposed outside the body, said external portion having an opening for connection to a source of suction and having an internal end portion to be disposed in the proximal segment of the small bowel, and a mid-portion adjacent to the internal end portion to be disposed in the stomach, said internal end portion and said mid-portion each having at least one orifice for intake of matter to be discharged from the body; a feeding lumen having an external end portion to be disposed outside the body, said portion having an opening adapted to receive food to be transported through the lumen and having an internal end portion to be disposed in the proximal segment of the small bowel, said internal portion having an orifice therein for the discharge of food; and means for securing the device to the patient's body through the abdominal and gastric walls such that the internal end portions of the aspirating lumen and the feeding lumen are located in the proximal segment of the small bowel, and said mid-portion of the aspirating lumen is located in the stomach, said feeding orifice being maintained at a location which is substantially three inches downstream of the most distal aspirating orifices, the portion of each lumen between the securing means and the lumen's external opening being continuous.

Claim 15

The invention of claim 12 wherein the feeding orifice is downstream from the last aspirating orifice by a range of 2-4 inches.
